Cov Ntsiab Lus Cov Ntsiab Lus ntawm Hu Rau Qhov Chaw Chaw HeadSet Cov Neeg Hais Lus Piav Qhia - Ib Phau Ntawv Qhia Cov Khw

1. Cov lus teb ntau yam

1) Dab tsi yog cov lus teb ntau zaus?
Cov lus teb ntau tshaj yog hais txog cov suab ntawm qis zaus (HZ) tias lub mloog pob ntseg tshaj plaws (HZ)

• Tsawg zaus (20Hz -250 hz): lub hauv siab resonance ntawm tib neeg lub suab, ambient suab (piv txwv li cov tshuab cua txias).
• Nruab nrab-zaus (250Hz -4 KHz): Qhov tshwj xeeb tshaj plaws band ntawm tib neeg lub suab (tshwj xeeb yog 500}
• Loj siab (4kHz -20} cmz): kev ntseeg siab (piv txwv li "s"), cov ncauj lus kom ntxaws ntawm lub suab.

2) Yuav ua li cas ntau zaus ntau yam cuam tshuam rau kev hu xov tooj?

• Kev ua tau zoo thaum nruab nrab yog qhov tseem ceeb tshaj plaws. Qhov zoo tagnrho: lub suab nrov lub suab yuav tsum tau ua kom zoo rau 300hz {2}}. 5kHz (lub sij hawm tseem ceeb heev.
• Sib npaug ntawm cov qes thiab siab ntau zaus. Ntau dhau lawm tsawg-zaus: npog ntsej muag tib neeg lub suab (xws li keeb kwm yav dhau los ua suab nrov); High-zaus yog qhov kaj heev: amplification ntawm cov hniav lossis lub suab nrov tam sim no (xws li "hissing" suab)

3) Cov lus teb lim kev ntsuas ntsuas ntawm bain lub mloog pob ntseg
Kuaj ntau: 20Hz - 20} khaz

• Suab hauv qab 50Hz (inaudible rau tib neeg pob ntseg)
• 10khz saum swb suab ntse (tib neeg ntseg ntseg ntseg tsis hnov)

Tib neeg lub pob ntseg tuaj yeem paub qhov txawv ntawm cov pob zeb ntau: 700Hz -1 cmz (nruab nrab-ntau hom suab)

(Rhiab heev kuaj cov lus tau ua tiav ntawm cov hais lus tiav)

2. Hais lus rhiab (DB \/ MW): Tiav cov khoom yuam kev ± 3dB

3. Kev Cuam Tshuam (ω)

• RJ Headset: Feem ntau siv 150 wb hais lus. Hauv cov xov tooj feem ntau siv 32 tus neeg hais lus, RJ Headset feem ntau yuav pom cov suab hais lus zoo dua.
• USB \/ hom C Headset: feem ntau muaj 150 xyoo, kev siv cov nyhuv tsis yog qhov sib txawv ntau!
• Qhov loj ntawm tus neeg hais lus imporance thiab qhov loj me ntawm cov kauj thiab cov tuab tuab ntawm txoj kab. (Qhov loj dua lub impedance, lub thinner thiab ntev dua cov hlau, cov coils ntau, tus nqi siab dua)

4. Hais lus loj thiab cov khoom siv
